Managing the "Breath" of the Bean: Engineering Vacuum Solutions for Roasted Coffee
Managing the "Breath" of the Bean: Engineering Vacuum Solutions for Roasted Coffee
Published on: January 12, 2026 | By Jialong Engineering Dept.
Coffee beans are chemically dynamic. After roasting, they undergo a process called degassing, releasing significant amounts of carbon dioxide (CO2). Simultaneously, the volatile oils that give coffee its aroma are highly susceptible to oxidation. For a packaging machine manufacturer, this creates a complex dual objective: evacuate oxygen to prevent rancidity, but manage CO2 to prevent package rupture. The solution lies in the advanced engineering of the modern coffee vacuum packaging machine.
While some applications utilize nitrogen flushing, the most stable long-term solution for bulk storage is vacuum brick packaging. An automatic vacuum packing machine for coffee exerts mechanical pressure during the evacuation cycle to shape the bag into a rigid "brick." This maximizes logistics density. Crucially, a specialized coffee bean packaging machine must be calibrated to ensure this pressure is sufficient to immobilize the beans but not high enough to crush them, which would alter the grind profile. This precise pressure control distinguishes high-quality food packaging equipment from standard vacuum sealers.
To handle high throughput, a coffee vacuum packaging machine must be integrated into a larger line. Jialong's automatic vacuum packing machine systems include automatic weighing, bag forming, vacuumizing, and box packing. As a dedicated packaging machine manufacturer, we ensure our systems can handle thick aluminum-foil composite films common in the industry. The heating bars in our food packaging equipment are designed to seal through contaminants (coffee dust), ensuring the integrity of every coffee bean packaging machine output cycle.
